Increasing thermal plant flexibility in a high renewables power system

摘要: Thermal generation is a vital component of mature and reliable electricity markets. As the share renewable in such markets grows, so too do challenges associated with its variability. Proposed solutions to these typically focus on alternatives primary generation, as energy storage, demand side management, or increased interconnection. Less attention given demands placed conventional thermal potential for flexibility. However, foreseeable future, plants will have operate alongside new renewables an essential role accommodating increasing supply-side variability. This paper explores that has play managing variability through sub-system case study Northern Ireland, identifying significance specific plant characteristics system operation. Particular wind ramping need avoid excessive curtailment. Potential conflict identified addressing two challenges. Market strategies using existing fleet reduce impact resource are proposed, wider lessons from approach taken identified.
